Taking over the space that Christopher's once occupied, Subtle is a quaint and simple restaurant.
I randomly went for $5 Burger Night (which is every Wednesday) - although I don't eat red meat, there was a spicy black bean burger option I happily ordered (Bonus: they have since added a portabello burger). Everything was very good - the fries, burger, and gin martini w/ bleu cheese stuffed olives were all solid.
Happy Hour is also worth going to - 1/2 off appetizers, $5 martinis, and $2.50 beers. Note: Thursdays are $5 Martini Night and goes all night.
The menu is best described as semi upscale pub fare: a nice balance of comfort and elegant food options.
One thing I particularly appreciate is that they listen to their customers - they have been continually enhancing their menu based on the feedback received.
